Plants require carbon dioxide (CO2) for photosynthesis, the process by which they make simple sugars. Photosynthesis is essential for healthy growth. Most aquariums contain small amounts of carbon dioxide; less than the 5-15mg/l recommended for optimum plant performance. The CO2 Optimat is a simple way to add additional carbon dioxide to the aquarium, and thereby supporting healthy, lush plant growth.

How it Works
The CO2 Optimat delivers concentrated carbon dioxide to a diffuser in the aquarium. Here it slowly diffuses into the aquarium during the course of the day, increasing the carbon dioxide level and promoting good plant growth.

How to Use
Simply press the top of the CO2 Optimat to squirt carbon dioxide into the diffuser. These needs to be done once or twice a day, depending on aquarium conditions. Regular checking of the carbon dioxide level with a TetraTest Laborett kit is recommended, to ensure that the correct concentrations are being achieved. When the cannister runs out it can be replaced with a TetraPlant CO2 Depot.
